Figure 21: Manual KNX/IP interface configuration for ETS older than ETS4.2.
Note
The Gira S1 Windows client remembers the locally used port (starting with 35000) for each tunnelling
server from the remote network so that the connections created manually remain valid later on for a
new remote access connection to the same installation.
Remote access communication is specially optimised for KNX communication so that it still works
reliably even with slow Internet connections.
